Most Active Stock Options August 12, 2009

The top ten option contracts traded from greatest number of contracts to least on Wednesday August 12, 2009 are as follows:

1. Citigroup August 4 Call Options
2. SPDR S&P 500 ETF August 100 Call Options
3. SPDR S&P 500 ETF August 100 Put Options
4. PowerShares QQQ ETF August 40 Put Options
5. SPDR S&P 500 ETF December 90 Put Options
6. Citigroup September 4 Call Options

8. SPDR S&P 500 ETF August 101 Call Options
9. PowerShares QQQ ETF August 39 Put Options
10. SPDR S&P 500 ETF August 99 Put Options

Nothing too unusual today. I am guessing someone is expecting the last 6 days of trading before options expiration to be rather volatile. It looks as if someone opened a reverse iron butterfly option spread on the SPDR S&P 500 ETF (SPY).
